When it comes to the "Battle Rounds," the final duel is the matchup the
whole episode leads up to - the title fight.

This spotlight performance usually features seasoned performers or singers
with big, booming voices. It doesn't typically serve as a platform for two country-indie
vocalists under the age of 20 - artists whose combined career stage time is
less than what most professional acts have logged this year alone.

But when Danielle Bradbery, 16, and Caroline Glaser, 18, took to "The
Voice" stage to end week one of the season four "Battle Rounds," it wasn't hard
to imagine why they were in the prime slot.

Singing Corinne Bailey Rae's hit song "Put Your Records On," the young
singers proved talent isn't dependent on age or experience. Their duet was
sunny and entertaining.

"Girls, your performance was as refreshing as tangerine ice cream," Shakira
said. "I'm impressed by the uniqueness of your voice, Caroline, and by the
juxtaposition between the lack of experience that you (Danielle) have, and your
enormous talent."

Adam Levine told Danielle her performance was spot-on, and he described
Caroline's voice as "ethereal, magic and wonderful."

When asked about her talent in a phone interview Wednesday, Danielle
couldn't attribute it to any one thing.

"I don't know," she said. "I just - I mean, I don't have - never had
singing lessons; I've never had as much experience as I have now. And the
ability I have now I hope to grow. And I don't know, it just comes out on stage;
and whatever happens, happens, and I try to do the best I can."

When Caroline wasn't chosen, she became eligible for a steal. Coaches Adam
and Usher quickly placed bids for her services.

"Caroline, what you do just astonishes me," Adam said. "Man, I've gotta'
have you. You lost the battle, but you definitely have not lost the war, and I
want you."

Usher, who called himself "Gusher," as he gushed over Caroline, said, "I
love your voice. I love the potential of what I know I can do with you."

A floored Caroline, trying to both digest what the coaches said as they
fought for her, and to pick one, decided to join "Team Adam."

"I did not expect any of that to happen," she said afterward. "I am in
absolute shock, right now, that I am on Adam Levine's team."

Blake, in a post-show interview, said, "I'm a little bit afraid of the
combination of Adam and Caroline, because Adam probably has a little bit better
understanding of that singer-songwriter-type thing. There's no telling how far
they can go."

Caroline came into "The Voice" as a guitar-playing singer-songwriter. In a
phone interview Wednesday, she said her time on the show - in the blind
audition and "Battle Round," and working with Blake and Adam - has taught her
how to be a better performer. Prior to this experience, she was most
comfortable singing behind her instrument. Now, she has confidence taking the
mic and walking the stage.

Danielle and Caroline both advanced to the "Knockouts," which begin airing
next week.

The "Battle Rounds" continue Monday at 8 p.m. on NBC. For more on "The
